This invention relates to improvements inmeans for mounting electrically driven oil burners in connection with'the furnace or firebox in which the burner is located, and particularly represents improvements over the structure shown in my Patent No. 1,609;

, 995, dated November 30th, 1926. a

In this previous apparatus the motor and parts of the burner structure. were enclosed in a housing extending from the outer end. of the supporting base of the structure to the firebox openin so as to form an air passage to the fire ox whose opening and closing couldbe controlled by a properly positioned damper. This housmg was rectangular in cross section, of consi erable len th and of a flexible fabric throughout. %his arrangement provided the desired vibrationless connection feature but proved awkward and cumbersome to appgy or detach when necessary, and since it ten ed to s'agintermediate its ends a neat appearance could not of course be maintained. The principal object of the present in vention' therefore is to improve 'upon this housing structure by making the greater portion of the same of a rigid and permanently attached character, and the remainder between the firebox and the rigid housing quite short and of flexible fabric, connecting the firebox and rigid housingin such a manner that it may be easily made, applied and removed, while functioning just as efliciently for its purpose as the previous arrangement. v

A further ob'ect of the present invention isto construct t e rigid portion ofth'e hous-j Y ing in such a manner t at the various ope'rating units of the oil burning' structure, enclosed within the rigid housing, are readily rendered accessible whenever necessaic'ly without detaching the entire housing an without dismountmg the fabric housing portion. At the same time these operating units are normally completely enclosed and thoroughly protected against possibility from; contact with exterior objects.

A further object of the invention is. to produce a sim 1e and inexpensive device and yet one which will be exceedingly efiective for the purpose for which it is designed.

These ob ects I accomplish by means of such structure and relativearrangement of part as will fully appear by a perusal of the ollowing specification and claims.

or the burner, connected to the rotating parts of the burner 1987. Serial No. 178,885.

In the drawings similar characters of ref- I furnace is a rigid base 3. Projecting from the end of the base adjacent the firebox and formed integral therewith or rigidlysecured thereto in any suitable manner is a rigid extension 4. This extension is clear of the floor and projects into the furnace through the opening 2 in spaced relation to the si es and bottom thereof. Supports 5 project upwardly from the inner end of the extension and support a' burner 6 of suitable form, such as for instance as is shown in my Patent No. 1,582,552, dated April 27th, 1926, though other forms of burner may of course be mounted instead of the one shown. The general arra ementof the motor, burner and co-relat parts is substantiall as shown in my Patent No. 1,512,241, ated ctober 21st, 1924.

The base 3 supports a driving motor 7 said motor being operatively by a horizontal'shaft 8 which extends from .t e

motor to the burner through the open-1 fhe improved housing which I provide for enclosing the external operatin mechanisms of the burner structure and or forming a direct air passage or conduit to the firebox opening is constructed as follows:

Mounted on the base 3 and overhanging and enclosing a portion of the extension 4 is a rigid metal ousing structure 9. This housing surrounds and encloses the motor 7 and all other external operating devices and "parts such as the electric relays and other electrical units, the oil pump and control units and any other features which may be incorporated with the burner structure toform the complete apparatus. The housing 9 is divided into two longitudinally separated compartments 10" and 11 by a transverse panel 12 mounted on the base outwardly of the motor,

the electrical units" (not shown) being intended to be mounted on the outer electrical instruments mounted on the panel 12 is had through a normally closed hinged door 15 mounted on the outer end of the housing. Access to the chamber 10 is had upon removing a normally closed fixed cover plate 16.

The motor shaft 8 and the base extension 4 pro'ect through a common opening 17 provi ed at the end of the housing nearest the furnace, this 0 ening being preferably circular in form an being surrounded by an outwardly projecting flange in the form of an annular ring 18. This ring is the same size and concentrically alined with a similar rin 19 which projects outwardly from the ire ox opening 2. If said opening is rec- ;angular or square, the ring (which is smaller than the opening) is secured in place by projecting the same into the opening a certain distance and then filling in the space between the ring and the sides of the 0 enin with brick-Work, or the like as indicate at QOJin Fig. 2. A length of cylindrically formed or tubular non-porous fabric 21 such as asbestos cloth, fits over the rings 18 and 19 and is removably clamped in place to form an air-tight oint by suitable clampthere is no tendency for it to in bands as at 22. The length of this fa ric tube does not need to be very great and in any event is short enough so that sag intermediate its ends. 1

From the foregoing description it will be readily seen that I have produced a device as substantially fulfills the objects of the invention as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims.

Having thus described my invention what I claim as new and useful and desire to secure by Letters Patent is:

1. An oil burner installation for a fire box having a side opening therein, comprising, with a base member supported exteriorly of the opening, a burner inside the firebox and operating means for said burner mounted on the base outwardly of the firebox; a rigid housing structuremounted on the base and surrounding the operating ing outwardly from opening and supported exteriorly of side opening thereof and into the rigid housing.

2. An oil burner installation for a firebox having a side opening therein, omprising, with a base member. supported exteriorly ofv the opening, a burner inside the firebox and operating means for said burner mounted on the base outwardly of the firebox; a rigid housing structure mounted on the base and surrounding the operating means, a transverse anel dividingsaid housinghnto two cham ers, a hinged door for the outermost chamber, butremovable cover the housin of the ot er cham r.

3. An 01 burner installation for a' firebox having a side opening therein, comprising, with a base member supported. exteriorly of the opening, a'burner inside the firebox and operating means for said burner mounted on the base outwardly of the firebox; a housing structure mounted on the base and surroundin the operating means, said structure exten ing from around the firebox opening beyond the operating means to form an air passage a transversew panel in the housing outwardl of the 0 rating means, a damper in-sai panel, an an air opening in the housing outwardly of the panel.
